Inline skates with two brakes used simultaneously

ABSTRACT

The present inline skates have a braking system allowing the brakes to be used simultaneously. One embodiment of the invention comprises a frame with a rear wheel carrier and a braking wheel carrier rotatingly mounted on the frame through a first cylinder and an axle and interlocking through a notch on a braking wheel carrier and a fourth cylinder on a first rear wheel carrier while the first rear wheel and a braking wheel are rotatingly mounted on their respective carriers. Another mobile rear wheel is handled by its carrier rotatingly mounted on the second cylinder affixed to the frame. The braking force is regulated through a screw and a pair of friction cylinders. Carrier rotation limiting cylinders are affixed to the frame. The front wheels are standard fixed wheels rotatingly mounted on the frame.

TECHNICAL FIELD

1. This invention relates to a special kind of inline skates featuringextra efficient braking system. Such skates are a sports requsite. Asfar as is known the inline skates with similar characteristics havenever been invented or made.

BACKGROUND OF THE INVENTION

2. The object of this invention is to create a braking system for inlineskates which makes it possible for two brakes to be used simultaneosly.This invention is sharply contrasted to a single brake braking system(with all its variations) widely practiced today which is highlyineffective. Namely, it allows the skater to use one brake only (duringbraking action) which causes the problem of balance. To solve theproblem of balance, the skater mast use a brake up to 30-40% of itsactual braking power.

3. By contrast pure braking system by putting to work the brakes (at thesame time) eliminates the problem of balance and allows both brakes tobe used up to 100% of their braking potential from the very beginning ofthe braking action.

SUMMARY OF THE INVENTION

4. The main characteristic of inline skates with two brakes to be usedsimultaneously during braking action. This kind of performance isachieved by the specific constructon of the frame, the main feature ofwich is the introduction of the mobile rear wheel working closely withthe mobile braking wheel during braking action. The said wheels are mademobile through their respective rotating carriers. A pair of rear wheelcarriers rotate around cylinders incorporated in the frame while a pairof braking wheel carriers rotate around the ends of the same axle. Thecarriers of both said wheels are interlocked during skating through thenotch (on one end) of braking wheel carrier clutching (hooking) thecylinder affixed to the rear wheel carrier. Once the braking action isover, both carriers are pushed back by their respective springs intotheir starting position to be interlocked eventually.

DESCRIPTION OF PREFERRED EMBODIMENT

8.FIG. 1 Shows an inline skate with frame 1 affixed to the boot. Firsttwo wheels 2,3 positioned inline on the frame 1 are standard fixed-nonmobile wheels. They are followed by two (inline) mobile wheels 26,4. Thereal wheel 4 and the braking wheel 5 make up the braking system to beexplained in detail.

9. The rear wheel carrier 7 is rotatingly mounted on the cylinder 29affixed to the frame 1 (FIG. 1,3). The spring holder 14 are affixed tothe inside of the frame 1 and to the rear wheel carrier 7 holding thesprings 13 the purpouse of which is to push back the rear wheel carrier17 (once braking is completed) to their starting position (FIG. 1), tillthey touch the cylinder 17 affixed to the frame 1 which limits theirbackward rotation.

10. The axle 12 is affixed to the frame 1 through a pair of screws 24,and has fixedly mounted hallow cylinder 21 on with its mid section 20(FIG. 3) (notch) against which one end of the spring 19 rests. The notch8 on one end of the braking wheel carrier 6 clutches the cylinder 9affixed to the rear wheel carier 7, to keep the rear wheel 4 firmly inits working position during skating. On the rear end of the frame 1there is the braking wheel carrier 6 rotatingly mounted on ends of theaxle 11 which is fixedly mounted on the frame 1 through a pair of screws25.

11. A pair of springs 19 (FIG. 2) are mounted on the axle 11, restingwith one end against the noch 20 of the hollow cylinder 21 and withother end against the spring holders 15 affixed to the braking wheelcarrier 6. By pushing the braking wheel 5 to the ground (mounted on oneend of the braking wheel carrier 6) a pair of springs 19 help the twowheel carriers 7,6 interlock once braking action is completed. Thebraking wheel 5 is rotatingly mounted on the axel 22 and constantlypinched with a pair of rubber cylinders through the screw 23 whichregulates the bracking force of each brake. The rear wheel carrier 7 andthe braking wheel carrier 6 are interlocked during skating (FIG. 1)through the notch 8 (on the braking wheel carrier 6) clutching thecylinder 9 affixed to the rear wheel carrier 7.

12. The third inline wheel 26 is mobile and is rotatingly mountedbetween a pair of its carriers 30 also rotatingly mounted on thecylinder 28 affixed to the frame 1. During skating the carrier 30 restsagainst a pair of cylinders 31 affixed to the frame 1 due to the anglebetween the ground and the carrier 30. Once braking is completed a pairof springs 32 push back the wheel carrier 30 till it touches thecylinder 31 (FIG. 1). The spring holders 33 affixed to the inside of theframe 1 and the wheel carrier 30 hold the said springs 32.

13. How the braking system works? During skating (FIG. 1) the brakingwheel 5 is above the ground and the carriers 6 and 7 are interlockedthrough their respective parts, the cylinder 9 and the notch 8. Thethird wheel carrier 30 under the body weight and the angle between thecarrier 30 and the surface rests against the cylinder 31. To engage thebrakes the skater should lift the front wheels 2 of both skates. Asresult, the braking wheel 5 touches the ground and their carriers 6start to rotate around the axle 11 counter clockwise till the carriers 6touch the cylinders 10 affixed to the frame 1. The said rotation of thecarrier 6 allows its notch 8 to release the cylinder 9 of the rear wheelcarrier 7. As result, under the body weight the rear wheel carrier 7starts to rotate clokswise around the cylinder 29 while the rear wheel 4starts pushing the third wheel 26 also clock wise. During the brakingaction the skating is done on the wheel 3 and the braking wheel 5 whilethe body weight is almost entirely on the braking wheel 5 because themobile wheels 26,4 get disengaged rotating idly. Once braking iscompleted the skates get lifted (one at the time) off the ground whichcauses the springs 32,13,19 to push their respective wheel carriers30,7,6 into their working position (FIG. 1) while carriers 7 and 6 getinterlocket again as result.
